Script that stays on the same page
Hello,
For my server, I need to write some script that will be 'regularly'
triggered (GET or POST), but that will NOT send the user to another page. The
user must stay on the same page he is, without ANY html being exchanged as
a result of the script.
This will be used to change parameters on the user's session, but since
those params will not affect the page the user is currently looking at, there
is no need to send HTML back.
So, 1/ can it be done ? 2/ How ?
TIA,

IIRC, NPH scripts are a source of bad karma with HTTP/1.1 because they stop
Apache dealing effectively with proxies, amongst other things.
Best Regards,
Howie.

I would try using a Non-Parsed-Header (NPH) script and return something like
this:
print << "END";
HTTP/1.0 204 No Response
END

www.macconnection.com or www.pcconnection.com do a nice job of this.
see any of their 'smart selectors'... every time you select a menu
option, the number of items 'found' by the /server/ scripts, based on
the users' new parameters, pop up into a text box. very slick.

It's generally not a good idea to follow up a user action with a page
that doesn't change... The lack of feedback makes people very nervous.
Notwithstanding, you can accomplish this by sending back a Status: of
204 (No Change) and a content-type: of text/html -- with no entity
body. The browser will leave the current page displayed, with no
indication of a reloaded anything.
